Microphones that are used for a long time in the field can break or start to fail in sensitivity. That's why you need to check microphones regularly. Simple microtesters are available at Veldshopnl. But for a more extensive test of microphones you can rely on our expertise.
We test the sensitivity of the microphone over the frequency range of 15 to 95 kHz and compare it with the results of a reference microphone of the same type. An example of such a test can be seen in the accompanying illustration below.
At this moment we can measure the following type of ultrasonic microphones:
We are working to extend this test to microphones from, among others, Anabat, EcoObs and Wildlife Acoustics.
Do you have doubts about your microphone, or do you want to have all your microphones checked before the start of the season? Please contact firstname.lastname@example.org so that we can make a customized quotation.
You can also "order" the test directly online and send your microphone to us, so we can get started soon.
